Specification of Letters Patent. Patent ea July 31, 1917,

Application fiid oblbb r 31, 1916. Serial No. 128,671.

To all whom it may concern:

Be it known that I, JAMES FLQYD JARRELIFQ a citizen of the United States, and a resident of Longmont, in the county of Boulder and State of Colorado, have invented certain new and useful Improvements in Beet-Seed Cleaners, of'which the following is a specification; p I

My invention relates to means for separating seeds berries, and the like from dirt,

leaves, twigs, or. other matter and among.

the main objects thereof are to provide "a machine for thls purpose having a relatively great capacity through the useof a plurality of cleaning units, which units are caused to travel while held in inclined planes and to be agitated at one point whileheld steadily all other 'points during such travel, to provide'means for adjusting the inclination of the said units at will, to provide controllable means for leading the material to be cleaned to the severalunita; to provide means for readily detaching said units when such detachment is desired, to provide means for conveying the cleaned material to a suitable receptacle, to provide means for conveying the refuse from the machine, and to providemeans for repeating thecleansing operation upon material'not thoroughly cleansed, andlto provide such a machine in a compact form adapted either for installation in a building or for use in a field; inthelatter use being readily moved as by the'provision of suitable wheels or rollers.

My invention is fully describedin the following specification, of which the accompanying drawings form a part, in which like characters refer to like parts in each of the views, and in which:

Figure 1 is an end view of one embodiment of my invention, partly broken away Fig. 2 is a rear view thereof, in the direction of the arrow in Fig. 1;

Fig. 8' is a top plan View of. one of the cleaning units removed from the frame;

Fig. 1 is a section taken on of Fig. 3; a v y the line 4-4 Fig. 5 is: a detached view of an agitator which I employ; I

Fig. 6 is a fragmentary view of a detail for verticallyadjusting one side of each of the cleaning units;

Fig. 7 is a section taken on the line 77 ofFig.6;

Fig. 8 is a fragmentary detail View ofath'e means provided for vertically adjusting the othler side of each of said cleaning units; Fig. 9 is a section taken on the. line 99 Referring to, the drawings,- 10 represents a frame for supporting. the operative parts of the device including a vertical casing 11 for an endless conveyer 12 of thebucket type in operative connection with-upper -and} lower shafts l3 and 1d the former of which is in operative connection with 'a power shaft 15 from. a suitable prime mover, not shown, and the lower endof the casing 11 is adapted to receive the seeds or other matter to. be cleaned. 1 i

The seeds upon being elevatedby the conveyer 12 are dropped into a hopper 16 at the top of the frame 10"and the bottom of which hopper has a plurality of chutes l7- leading. downwardly therefrom to spaced vertical positions at one side of the frame; and said hopper contains a serrated roller 18 and an adjustable gate 19 the former of which is connected with the prime mover in any desired manner, a belt 20 being shown. X o.

The frame 10 supports a plurality of cleaning units 21 horizontally arranged for the length of the frame and held at an inclination for the width of the frame, one side, of each unit having ears 22 thereonin pivotal engagement with carriers 23 vertically adjustable in the frame by means of screws 24,and the other side of each unit having hooks 25 thereon for engagement with oneqor more vertical rack .bars 26 whereby this side may be vertically adjusted, different materials to be cleaned often and the several chutes 17 lead to the higher sides of the respective cleaning units, and at one end of said units, Figs. 1 and 2.

Each of the units 21 consists of a frame formed of side bars 2T7and end bars 28 the former of which carry bearings for shafts 29 and 30 adjacent opposite ends of said frame, the shaft 29 being immovable with respect to said side bars whereas the bear ings of the shaft 30 are preferably adjustable toward the respective end bar, as by means of screw members 31 to adjust the tension of an endless blanket 32 carried by rollers on the two shafts, and said shafts are preferably connected by means of a belt or chain 83 passed around pulleys or sprocket wheels 34: onsaid shafts.

lhe shaft 29 is provided with a bevel V pinion 35 normally enmeshed with a similar pinion 36 on a vertical shaft- 37 held in the frame 10, the shaft 37 carrying a pinion 36 for each of the cleaning units and being con nected with the prime mover, as by means of gears 38 and 39, pulleys 40 and 41, and a belt 42-, or in any desired manner.

The side bars 27 carry a platform e3 for approximately the distance between the shfts 29 andSO interrupted at 44c and serving to support the upper portion of the blanket 32 against or flapping, a tapered angular beater 45 being carried by the side bars 27 in the space where the plat form is interrupted, a pulley Q?) on said beater being connected with a pulley 47 on the shaft 30 by means of a belt as or its equivalent, said beater bearing directly against the under surface of the upper portion of the blanket and serving, in its rotation, to agitate said blanket at this point only, the platform 43 holding the blanket steady except at this point.

Arranged adjacent the lower sides of all of the units 21 is a chute 49 for leading the seeds to a receptacle 50 whence they may be removed, as by a conveyer 51, to any suitable point, and I provide a receptacle 52, beneath the ends of said units toward which their blankets move, for the culls which may be led to a desired point as by means of a chute 53.

As shown in Fig. 2, nated at its lower end in a hopper 54 extending about threefourths across the length of the machine, and cleaned seed will drop thereinto for approximately threefourths of the distance of travel of the several blankets, at their lower edges, and I provide a supplemental hopper 55leading to a receptacle 56 for the remaining" onefourth of blanket travel, also at the lower edges thereof, this being for the reception of only partially cleaned seeds which are carried upwardly to a hopper 57 by means of a conveyer 58 and deposited upon he the chute 41-9 is termilowermost unit adjacent the agitator or heater 4 5 thereof, these seeds being are cleaned and being deposited in the receptacle 50, the culls being carried to the receptacle 52.

The seeds having hard and smooth surfaces. usually round, will roll down the 1nclines of the respective blankets and the culls will adhere to said blankets until they are removed by scrapers 59 atthe far end of blanket travel, Fig. l, and the several beaters assist in separating the seed from the culls though only at one point of blanket travel.

It will thus be seen that the seeds to be cleaned are deposited upon a plurality of cleaning units having t-lilVQllllQ' blankets arranged at an incline down which the seeds roll to a suitable receptacle, agitation of the seeds occurring at a predetermined point and the blankets being held steadily for the greater part of their travel by the plat forms thereunder, the degree of feed to said units being under control by the gate 19, and partially cleaned seed are submitted to a re-cleaning operation,

The units are readily removable from the frame when such removal is desired, and the inclination thereof is variable to adapt the machine to different products, and the blankets be readily removed from the respective units for substitution, cleansing, or repair.

While I have shown a practical embodi= ment of the invention, it will be apparent that structural changes may be made thereover without departing from the spirit of the invention or sacrificing its advantages,"

provided that such changes comes within the scope of the appended claims, and I reserve the right to construct the machine in stationary or transportable form, and to provide any desired number of the cleaning" units and of any desired size.

Having .fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. A seed cleaner, comprising a frame, a cleaning unit held at an angle therein, and means for leading the cleaned seeds and the culls to different points, said unit consisting of a roller carrying frame, an

endless blanket movable therein, a fixed 7 platform supporting the upper portion of said blanket to prevent upward and downward movement thereof, said platform bemg interrupted at one point adjacent its end and means at said interruption for agitating said. blanket at said interruption only.

A a cleaning unit held at an angle therein, means for leading the cleaned seeds and the culls to different points, a supplemental seed cleaner, comprising a frame, a
